Find a LHBS. They're only a couple bucks, and I have to think that you'll pay twice the cost of the caps in S/H. If you don't have an LHBS, I think Midwest Brewing Supplies accepts paypal.
No LHBS anywhere close. It cost me less in shipping than it would in gas to drive to the closest LHBS, so it's online shopping for me. I'll goto Midwest. Thanks!
